Very friendly staff. The rooms are large and clean, but nothing fancy. They also have triple rooms and family rooms with two separate sleeping areas. Breakfast was very basic, but available from 4.30, so perfect for our early departure flight. It's very close to the airport so a good option for early departures or late arrivals.
This is also the most important drawback, because people will arrive and leave all night and the doors won't stop all the noise.
The free shuttle to the terminal is very useful.
It is not in the city centre so you will need a car if you want to go to Keflavik city centre (f.e. for dinner).
They have a car rental in the hotel, but you can also ask other car rentals to bring your rental car to the hotel or pick it up at the hotel. This might save you one rental day.More
